With a structure as-"herein specified the necessity for removing a screw threaded closure member is eliminated and at the same these changes as may fall within the scope of the appended claims, I consider Within the spirit of my invention.

I claim: 7

1 In combination, a body having a bore, annular fiat shoulder at one end of the bore, a closure disk, said disk being engageable with the shoulder, radial fingers on and in a plane with the body of the disk to space intermediate portions of the disk from the wall of the bore, guide legs on said fingers engageable with the bore'wall, and spring means normally yieldably seating the disk upon the shoulder,

2 A closure disk'comprising, a body por-" tion, a set of eircumferentially spaced radial lingers at the d sk periphery, sald fingers being in a plane with the disk body, and 7 guide legs integral with the fingers and at right angles thereto.

In testimony whereof, I my signa
